Here’s a good tip for you if you’re a fan of the endless runner Jetpack Joyride. On the Windows 8 and Windows Phone 8 versions, just about everything in the Stash (the game’s store) is free today.

Bug or giveaway? We’re not sure but it’s worth checking out.

Indeed we bought just about everything we could from unlocking levels to new outfits to utilities on our Surface Pro. On Windows Phone we were able to do the same as well, collecting a ton of achievements too. However, after about every second “free purchase” the game would freeze on our Lumia 925 and Lumia 1020, making the process…well, a process, though it seemed to be random too. We didn't experience the same on Windows 8 though, making it much easier.

“There was some sort of a crash yesterday, I had lost all credits and Jetpack Joyride was not working. But they are now back and items are free.”

The game does look to still be having stability problems as on an initial load it seems to be crashing the game, at least on three of our phones. After that, it crashes after a few purchases, requiring us to hit the Windows key, jump back into Games and re-launch. It eventually exits the game and we have to repeat the process.

On our Surface Pro, just about everything is free

We’re not sure if Halfbrick is doing this to amend for yesterday’s crash (plausible) or if it’s a glitch. Regardless, you are more than welcome to give it a go.

If you haven’t downloaded Jetpack Joyride yet, you’re really missing out on what is an excellent game.

Update: A ton of you are noting in comments that you don't have anything for free, so here at WPCentral, we must have magic phones and tablets as our pictures don't lie! Now pardon us, we're going to go use our Golden Piggy Pack and blast money at scientists. (But seriously, sorry if you can't get this deal. We verified with a few people that this works.)

Update 2: People are having luck by uninstalling and reinstalling the game, then trying the Stash. That makes sense as we fresh installed the game on our three phones.

I actually prefer them NOT being free. It's something to actually work for. If they were all free... I probably wouldn't want to play the game anymore. That said... I might've taken some of the more expensive items because I doubt I'll play the game that much to unlock everything.

I feel the opposite. I stopped playing because there was too much grinding just to get basic upgrades. Now I have almost all the upgrades and only the most expensive items still aren't free. The game is fun again, so I'll be playing it more to get the still-paid items

Uninstalling and reinstalling works. Just freezes alot and now it's freezing my phone twice as I've been trying to get the last free items, freezes every time I but more than one free item....scary that it froze my phone but I have an 820 so I just pulled the battery out but yea...

Wait a min now everything I had purchased for free is gone!!! Omg noooooo!!! And my coins are down to zero!!! That's not fair...everything is free still but damn i don't wanna start purchasing and it freeze on me again :(

Perhaps pulling battery was your problem.. Instead, when it freezes, try pressing Windows button, then back button... Once it resets to start screen, go back in and purchase 2 more items. Rinse and repeat.

Managed to get all the free clothes in one go, and the free gadgets, but jetpacks and vehicle upgrades freeze up. Only get one if you're slow, three if you're quick. Re-installed on my WP8 to get the free stuff since I hadn't played it much, but don't think I'll re-install on Windows 8. Getting close to unlocking everything on that anyway and not confident it'll remember where I'm up to when I re-install.

I uninstalled it and reinstalled it and now almost everything in the stash is free. The only thing is that when installing the jetpacks, only 2 can be downloaded then it freezes. What I do is go to the multitask street (hold on the back button) and go back one screen. Then press the back button again to go back to Jetpack Joyride. Then it closes. I then have to reopen it and continue buying the free stuff.

I'm not really interested in losing my progress for freebies...and it's locking up this evening, it seems, while trying to access the leaderboards.
In a perhaps related note, the new version of Fruit Ninja (also Halfbrick) was locking up and having fits on me this morning. Server issues?
When does their new one come out? Colossatron?
Just looked at their Facebook page? Man, we need an update to get some of those other costumes and vehicles...

I had that happen to me with a different Xbox game. Sounds like the uninstall/install failed. Try going to the actual windows phone website www.windowsphone.com and log in there. Go to past purchases and follow the directions to "push" the reinstall to your phone. If the game installs, but shows up under the non Xbox section in the games tab, uninstall it. Then you can reinstall anyway you like, and it should work.

Got everything for free, my phone locked up, restarted, and I lost EVERYTHING (including what I had gotten before today). Probably just gonna uninstall...

UPDATE: I turned off my data connection, and my WiFi, and then downloaded [almost] everything. Then closed the app, turned on my Data/WiFi, launched the app again and now I have everything saved. The game plays fine, no issues at all. Just had lots of freezes when downloading the stuff.

Seemed to clear up after a couple of reboots (and draining most of the battery). Many of the purchases hadn't 'stuck' (they showed as not purchased) but I was able to go through them all again without any more crashes.

This is legit. I didn't have the game so I downloaded it in order to grab all the goods. It worked great except for one thing.. Kept freezing after each second purchase. That's for jetpacks and utilities I think? Still, grabbed a nice 40G for just tapping on my screen. And got the materials to earn the rest of the achievements at my convenience. :) It works.

disconnect from the internet
go in buy everything that is free(not everything is free)
close the game
reconnect to internet
use your new stash to unlock achievments and get more coins
buy everything else

*Tip* if you want it to stop freezing uninstall, reinstall, then soft reset your phone. It worked like a charm for me, I have over 200 super boosts and bombs and lives bought and almost everything in the store without a single freeze.

As said, Uninstall and re-install to get nearly everything for free....did it on my 920 and Surface RT.
Happy days...cant stop it crashing and having to relaunch after a few purchases on my 920 though.

Wtf are they doing with this game... Since yesterday the game freezes after like 5-10 minutes of play.
I even had to soft reset once.... (btw why are my background tasks not working after soft resetting? chronos and weather flow)
Now they make everything free (bug or intented)... great, but the 2 problems: this kills the fun of the game, and more importantly the game is
STILL FREEZING... ffs (even not doing anything with the stash).
These made me delete the game... gz for the devs (or whoever responsible)

Tried uninstalling and reinstalling. Once it finished, my entire phone became incredibly unstable, actually freezing. This obviously caused great distress to me, because as we all know, Windows Phone is extremely stable and never crashes or freezes. Thankfully, a soft reset worked, bur once I rebooted, I noted it was trying to install itself again... This was too weird, and I'm worried it might compromise my phone, so just to be safe, I canceld the install and will leave it that way.

It's a shame, I've now likely lost several weeks of progress in that game, but hey, it's better than my phone being bricked, and I kinda deserve it. I uninstalled a stable version in the pursuit of free stuff, which came at the cost of a seemingly unstable build.

My phone is fine, and I'll await a fix. It just means I've got to work my way up the ranks... Again.
